A REST API is a network interface that exposes resources and operations through HTTP using representational state transfer conventions.
A REST API exposes Podman as a socket-activated service, allowing remote clients to manage and launch containers through HTTP-based interfaces. section 1.3.6
Podman provides two API paths with different compatibility and feature goals:
Podman mode exposes advanced Podman features through podman-py and other remote clients. section 9.6
The service supports rootless and rootful operation and can serve Linux-based remote container workflows. section 9.0
Remote management
Use `podman --remote` to communicate with a local or remote service, and `podman system connect` to manage SSH connections to remote Podman instances. section 9.0section 9.6
How Podman in Action: Secure, rootless containers for Kubernetes, microservices, and more covers it
How deep it goes
Defines socket activation, API modes, bindings, and SSH communication without detailing request formats.
Examples
Demonstrates docker-compose, Python bindings, podman --remote, and podman system connect workflows.
What it assumes
Assumes basic Podman command-line familiarity while introducing remote services, client libraries, and Docker compatibility.
What you can do after
Operate remote Podman through REST clients, Python bindings, Docker-compatible tools, or SSH connections.
How it connects
Links container management with Docker API compatibility, podman-py, docker-py, docker-compose, SSH, and rootless operation.

HTTPuses · HTTP is a standardized application-layer protocol that defines request-and-response messages for transferring resource representations between networked systems.
GraphQLalternative to · GraphQL is a query language and execution specification for APIs that lets clients request and manipulate data through a schema.
gRPCalternative to · gRPC is an open-source remote procedure call framework for defining services and invoking them across process or network boundaries, commonly using Protocol Buffers and HTTP/2.
web servicekind of · A web service is a programmatic software interface that exposes functionality or data through web technologies or network protocols, typically HTTP.
schema registryused by · A schema registry is a service that stores, versions, and provides schemas for structured data, often validating compatibility between schema versions.
stateless systemuses · A stateless system handles each operation without relying on state retained from prior operations, though state may be maintained externally.
